Question

我在Jet SQL中有以下查询。基本上每个子查询A，B和D在最终表中生成一列。如果我按原样运行查询，则会在条件表达式中出现“数据类型不匹配”。如果我删除A，B，D中的任何一个它工作正常。我试过改变A / B / D的顺序没有效果。

如果我自己拿走每个A / B / D，他们就会执行罚款。

感谢您指点我正确的方向。问题是Nulls。如果我添加以下内容则一切正常。

SELECT Z.accCategory, Z.ID, Z.Account, 0 as Spent, 0 AS Allocated, 0 As CurrentAllocated 
FROM (
SELECT Accounts.accCategory, Accounts.ID, Accounts.comment AS Account, 0 AS Total FROM Accounts INNER JOIN Items ON Accounts.ID = Items.accFrom WHERE Items.ID=0
) AS Z 
GROUP BY Z.accCategory, Z.ID, Z.Account
UNION
...
